A negative value is taken as zero. If the value is beyond the end of the sequence, an empty
sequence is returnedlength - the number of items to be included in the result. Specify Integer.MAX_VALUE to
get the subsequence up to the end of the base sequence. If the value is negative, an empty sequence
is returned. If the value goes off the end of the sequence, the result returns items up to the end

In the case of data types that are partially ordered, the returned Comparable extends the standard
semantics of the compareTo() method by returning the value SequenceTool.INDETERMINATE_ORDERING when there
is no defined order relationship between two given values.
For comparing key/keyref values, XSD 1.1 defines that a singleton list is equal to its only member. To achieve this, this method returns the schema comparable of the singleton member if the list has length one. This won't give the correct ordering semantics, but we rely on lists never taking part in ordering comparisons.
